I was in Cleveland on business and the valet pointed this place out. In a town that rolls up the sidewalks after 9:00, it was nice that I could not only get a great beer selection, but some decent eats as well.
The bar is very narrow and I'm sure it's tough to get around if crowded. I had no problems with service. As much as the bartenders had to deal with some of the meatball crowd, they were cool and had good suggestions on beers to try.
In any case, great place if you want a late night beer or grub. My impression is that it could get a bit out of hand, so I would avoid when the local teams are playing at home.
